• Digital dermatitis vs heel horn erosion

  Digital dermatitis

  • Raw or hairy skin lesion
  • Usually rear cleft or heel skin

  • Often beside a wet cleft
  • Horn damaged from the skin side

  Neighbors in a dirty cleft. Still two names.

Field notes on this focus

1. Note 01Digital Dermatitis Staging: M0 to M4.1M-stages (M0–M4.1) turn “hairy heel wart” into a herd language for active vs chronic lesions — staging drives treatment urgency, footbath strategy, and whether chronic cows are seeding the pen.Knowledge level in this topic: Advanced. Mechanism and stacked risk in this topic — assumes the first-pass frame.Advanced3 min · 2026-09-15
2. Note 02Footbaths: Prevention, Not TreatmentA footbath is a herd prevention tool for digital dermatitis pressure — not a cure for an active painful lesion waiting in the chute. Concentration, cow passes, and cleanliness decide whether the bath reduces new cases or just paints dirty heels.Knowledge level in this topic: Intermediate.

3. Note 03Digital Dermatitis in Heifers: Prevention Before First LactationHeifers that meet endemic digital dermatitis before first calving pay for it in early lactation — prevention in the rearing pen beats chasing first-lactation ulcers after they hit the parlor.Knowledge level in this topic: Intermediate.

4. Note 04Footbath Design: Length, Depth, Cow Passes, and CleanlinessA footbath only works if every cow gets enough clean contact — length, depth, and how often the bath is refreshed decide whether heels are treated or just splashed with dirty solution.Knowledge level in this topic: Intermediate.
